The 1250 can outrun the 3000 by a factor of two under identical percentages, or run head to head for the same time.

SMART-UPS 3000 is a 48V based or 4 batteries. Smart-UPS 1250 is a 24V based or 2 batteries.

Finally, here is what Carl Erhorn has to say about batteries:

Hi, Folks.

Well, Kern was absolutely right. The problem with my UPS was batteries. It was unexpected though, because there was no indication of a bad battery right up until the UPS failed entirely.

For those who might encounter the same thing, and don’t know what’s happening (I didn’t either), here’s what happened.

A week or so ago, I turned on one of my SmartUPS 700-NET models. The load is a small dual P-III unix server (Solaris 8, X86) and a 4MM tape drive. During the normal selftest that runs when you first turn on any APC UPS, the UPS ’freaked out’. The alarm stuttered at about 4 or 5 beeps per second, and all the panel lights flashed spasmodically, as if something was loose inside the UPS.

I turned off the UPS and it’s load, then turned the UPS on again. This time, everything seemed fine. I booted the system that was attached, and there were no problems. The status monitor showed 9 minutes runtime (which indicates fairly low capacity), but the batteries showed fully charged. I began to suspect a bad inverter in the UPS.

However, Kern told me that he suspected the batteries. So I took the UPS offline, put an old SU-600 in it’s place (just barely big enough to handle the startup peaks - I get an ’overload’ lamp lit for about 2 seconds during boot), and checked out the batteries. They did indicate that they were near the end of life, so I ordered a replacement set. Those came in on Friday, and after the initial charge, a complete charge/discharge cycle to recalibrate the UPS, and some testing, I put it back in service.

UPS control system specifications

APC UPS (Uninterruptible Power Supply) control systems are vital components for ensuring uninterrupted power supply and protecting critical equipment from power interruptions, surges, or fluctuations. Designed by Schneider Electric, APC UPS systems are renowned for their high quality and reliability. They utilize advanced technologies and features to suit diverse applications, from home offices to large industrial settings.

One of the main features of APC UPS systems is the ability to provide backup power during outages. This is achieved through a battery system that activates immediately when the mains power fails. This seamless transition minimizes downtime and ensures that electronic devices continue to operate, protecting data integrity and equipment lifespan.

Another significant characteristic of APC UPS systems is their intelligent management capabilities. Most models come with PowerChute software, which provides users with real-time monitoring of power conditions and the status of the UPS. This software allows for graceful shutdowns of connected devices during extended outages, thereby preventing data loss and damage to devices.

APC UPS systems also incorporate advanced technologies such as Automatic Voltage Regulation (AVR). AVR technology ensures that the output voltage remains stable by correcting minor fluctuations without switching to battery mode. This not only prolongs the battery life but also provides a consistent power supply to the connected equipment.

Thermal management is another critical aspect of APC UPS control systems. The design often includes efficient cooling systems that prevent overheating, ensuring optimal performance and longevity of the unit. Some models feature EcoMode, which reduces energy consumption and lowers operational costs by working at high efficiency only when battery backup is not required.

APC UPS systems are designed with scalability in mind. Users can easily add more batteries or connect additional UPS units to accommodate growing power needs. Features such as hot-swappable batteries and modular design facilitate easy upgrades and servicing without interrupting power supply.

In terms of connectivity, APC UPS products often feature multiple options including USB, RS-232, and network management capabilities. This enables users to connect remote management tools and integrate the UPS with existing IT infrastructure.

In summary, APC UPS control systems deliver reliability, efficiency, and advanced technology features that cater to a wide array of power protection needs, making them a trusted choice for individuals and businesses alike.
